Thanks to Brian for sharing with us:
“PSA: STAY HOME. People were out and about Washington, DC for the cherry blossom festival despite warnings to stay home to stop the spread of COVID-19. So I decided I would drive around with giant speakers on the roof of my car to tell people to create a public service announcement to stay home, stay safe, and practice social distancing during the coronavirus pandemic.”
Helps explain the decision to involve The Guard a bit more.
